Problems solved by technology

[0005] If the existing terminal equipment wants to expand the display viewing angle of the LCD, it is usually realized by using an LCD with a large viewing angle, that is, considering the LCD hardware, this will inevitably lead to an increase in the overall cost of the terminal equipment

Embodiment 1

[0026] Based on the above idea, the embodiment of the present invention provides a terminal device, such as figure 2 shown, including:

[0027] LCD1, controller 2 and CPU3;

[0028] LCD1 is used to display video images according to the received video data; the data lines and scanning lines of the LCD1 are drawn from the wide side, and the wide side of the LCD1 faces the top of the terminal device, and the narrow side faces the bottom of the terminal device end. The wide side of the LCD1 is equipped with a FPC (Flexible Printed Circuit, flexible printed circuit), and the other end of the FPC has a golden finger for connecting with a connector on the main board.

[0029] The controller 2 also has a random access memory RAM20; the RAM20 is used to store the next frame of video data to be displayed by the LCD1; the controller 2 is used to control sending the video data in the RAM20 to the LCD for refresh display.

[0030] The CPU3 is used to calculate the next frame of video d...

Embodiment 2

[0034] This embodiment provides a terminal device. On the basis of the terminal device in Embodiment 1, refer to image 3 , the controller 2 may specifically include: a refresh direction setting module 21 and a synchronization adjustment module 22 .

[0035] see Figure 4 , assuming that the upper left corner, upper right corner of the narrow side of the existing LCD, and the lower left corner and lower right corner of the wide side are respectively a, b, c, d, then the refresh direction of the LCD is usually a→b→c→d.

[0036] The refresh direction setting module 21 is used to set the refresh direction of the LCD1 from the upper left corner of the wide side to the lower right corner of the narrow side.

[0037] Because this embodiment reverses LCD1 (that is, the wide side faces the top of the terminal device, and the narrow side faces the bottom of the terminal device), without changing the position of each pixel in the next frame of video data to be displayed in the RAM. If...

Embodiment 3

[0070] This embodiment provides a terminal device. On the basis of the terminal device in Embodiment 1, the CPU is also used to reverse the next frame of video, and the video data in the RAM is reversed video data.

[0071] Since the video data in the RAM is inverted the same as the LCD, the picture on the LCD is displayed normally. The code in the controller does not need to be adjusted, but the CPU needs to calculate the next frame of video to invert, which increases the calculation burden of the CPU. Therefore, this embodiment has higher requirements for the CPU calculation capability.

Abstract

The embodiment of the invention discloses terminal equipment. The terminal comprises a liquid crystal display (LCD), a controller and a central processing unit (CPU), wherein the LCD is used for displaying video pictures according to the received video data; data lines and scanning lines of the LCD are led out from the wide side; the wide side of the LCD faces the top of the terminal equipment, while the narrow side faces the bottom of the terminal equipment; the controller is provided with a random access-memory (RAM) which is used for storing the next frame of video data to be displayed by the LCD; the controller is used for controlling the sending of the video data in the RAM to the LCD for refreshing the display; and the CPU is used for calculating the next frame of video data to be displayed by the LCD, and refreshing the video data stored in the RAM by using the next frame of video data. By reversing the LCD, on the premise of not improving the cost of the terminal equipment, the display visual angle of the LCD is widened, and the visual experience of a user is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a terminal device. Background technique [0002] Because LCD (Liquid Crystal Display, liquid crystal display) has the advantages of good image quality, relieve visual fatigue, large viewing area, no electromagnetic radiation, well-proportioned and thin body, low power consumption, etc., the display screen on the terminal equipment mostly uses LCD. [0003] As the functions of terminal equipment continue to be enriched, the consumer demand for terminal equipment continues to rise, resulting in an increasing usage of LCDs. The display viewing angle of an LCD is determined at the time of design and production. Usually, the viewing angle of the LCD on the existing terminal equipment seen by the user is relatively small, which affects the user experience. [0004] In the process of realizing the present invention, the inventor found that the prior art has at least the follo...
